#5: MF Global

The brokerage firm, led by former Goldman Sachs Chairman and former New Jersey Senator then Governor Jon Corzine, had $41 billion in assets before failing in October 2011. That put MF Global at #8 on the list of ten largest bankruptcies. A year later, $1.6 billion in customer assets were still missing and no SEC or DOJ charges had been filed. A predecessor firm with $33 billion in assets, Refco, failed in 2005.
